You can try view a sample 3d hsbs then switch to 2d mode on the fly (view only half of video resolution) to see if it works. I repeat, changing the view in the middle of playing not at the beginning. I get no signal error only when changing mode on the fly not at the beginning when kodi ask to display in stereoscopic or monoscopic.https://drive.google.com/file/d/0BwxFVkl63-lEX3RpYTNEMFZxcjA/view?usp=sharing

I have a similar update problem as @peerobo. Libreelec is installed on a SD card (with Android Vim_Marshmallow_Root_170603 image on internal storage). After updating to 20170801 using .tar method boot is stuck at Khadas logo.

LibreELEC 8.2 builds for Amlogic S905/S905D/S905X devices.
Read this first: [HOWTO + FAQ] Install community builds on S905/S905X/S912 device
Important notes:
These are unofficial, community supported builds so please post all bugs/issues in this…

If you forgot to use a new device tree or used wrong one and your device doesn’t boot:

don't panic!
if booting from SD/USB, simply connect SD/USB to your computer, download a proper device tree, rename it to dtb.img and place on SD/USB
if booting from internal:
Boot this build from SD card or USB with correct device tree.
Login over SSH and execute dd if=/dev/zero of=/dev/dtb bs=256k count=1 then dd if=/flash/dtb.img of=/dev/dtb bs=256k
Power off, remove SD/USB, boot from internal.

Thanks @balbes150 for the instruction. I think you should include it to the first post or update the command “install to eMMC” to copy dtb.img into eMMC, so no extra manual step for the user.
If I replace the new dtb.img in the eMMC, will your previous Armbian build function? (the one that use stocked dtb.img in eMMC)

The clean install (using the menu item “Reboot to install eMMC”), if the medium has the file “dtb.img” it is automatically copied to eMMC. When using the updates by using the “tar” in the eMMC memory is written to the image “kernel.img” which contains a (default) option dtb (which not corresponds to the model VIM). Therefore, the transition to the new kernel (and new dtb data), in update file “tar” needs a manual copying process. Either need to change the update script, something he was looking for the dtb file and if present he updated it (to the extent possible, I will think about how to do it better).

If you update dtb data in the images on external media where they used the automatic download dtb from the internal memory, you will need to manually add the old variant dtb (to add to the media file “dtb.img” from the image).

Assemble new version 20170807 of the LE for KVIM. The site is indicated by the suffix VIM. Note that in this version do not need to perform any manipulation of the DTB file. The required data are part of the image for recording to external media and in the TAR file. Please check how to work this version of VIM when you upgrade using the tar file and using a clean installation.

In this embodiment, a modified procedure activation TV. The system will attempt to obtain the possible settings from the TV, if this is not possible, it will use the previous version of the installation the screen resolution. Please check this option and write, if at system startup, there will be problems with the initial splash screen (the inscription LibreELEC at startup).

A few days ago I tried an update from 20170705 to 20170807 with the .tar method (using LibreELEC-S905.aarch64-17.3_20170807-KVIM.tar) installed on a SD card, but it didn’t work, the boot process stopped at the same place as before.

Putting the correct DTB file on the SD card fixed it. I haven’t yet tried the latest version 20170816 or a clean install.
